The Effect of Plant Supplements on the Development of
Artificially Weaken Bee Families
Quote: |
4. Conclusions
The purpose of the present research was to
determinate in the laboratory and in the field the
effect of different plant infusions and extracts on
honeybee colonies productivity. Studied
supplements were nettle (Urtica dioica), Protofil,
onion (Allium cepa), garlic (Allium sativum),
thyme (Satureja hortensis), Echinacea (Echinacea
sp.). Experimental groups were build out of
artificially weaken bee colonies.
Laboratory determinations show different
polyphenolic content in the studied plants, which
were correlated with the field experiments
regarding the production of brood surface.
If we make a classification of the used
supplements, regarding the growth of brood
surface comparing to control groups, we can say
that nettle infusion induced the highest growth,
followed by Protofil, garlic, onion, Echinacea and
thyme.

About 25% more brood from what I read, making the syrup from an infusion of 100g of nettles in 1 litre of hot water.
Interesting. |

Urtica dioica is stinging nettle Linky |
Oh, thanks. It was called Urtica Urens when I was at school ... All this reclassification is annoying at times. |
Urtica urens is the annual stinging nettle.
But I agree that the reclassification is a pain in the wossname.
Most of my books are now out of date, as they were ones I used at uni. |
Same here, but I can see the point. DNA technology has allowed us to see relationships much more accurately, and they can't say "Oh well, that was wrong, but we'd better leave it as it will annoy all those old fogeys who learned their taxonomy in the olden days."
My trouble is I now know both names, new and old, for some things but can't remember which is the up-to-date one. |
I didn't say that I don't agree with reclassification, I realise why the changes are made. And it's not just DNA technology that's enabled us to see relationships; taxonomical changes have been going on since Adam was a lad, with people realising that two people have classified the same thing, under two different names and having to revert to the older one - used to occur when someone was doing their Phd in a herbarium somewhere and came across a dusty old specimen that was collected back in 17someodd, putting it under a microscope and thinking "hmm, this looks very similar to......."
It's still a pain in the proverbial when you find that the expensive books you have on the shelf are now out of date and you can't afford to update them (and anyway the newer ones are not as well produced, well written or well illustrated as the ones you already have, it's just that they call Bluebells Endymion non-scripta instead of Scilla non-scripta, sorry Hyacynthoides non-scripta.) |

Sorry for bringing up an old post but I find the nettle feed very effective and new keepers might want to try it!
